For those who model with a North Wales theme (acknowledging, of course, that slate was/is also quarried in Pembrokeshire and the Lake District), I noticed today that bags containing as many slate chippings as you will probably ever need (unless, perhaps, you are contemplating a 1:24 diorama of the entirety of Blaenau Ffestiniog and the surrounding district) are currently available in the gardening section of that well known UK high street emporium where the price of (almost) everything in store is in the name!
